永磁真空断路器过零分断保护电路的研究与设计
资料介绍
为了避免断路器在大电流/电压下分断电路,产生电弧、电火花,对系统安全造成危害,对永磁真空断路器过零分断保护电路进行研究,设计了零点检测电路.该电路使得断路器在电压电流过零点时进行分合闸,达到无弧可灭的目的,提高了系统的安全性与可靠性.
In order to avoid the breaker generates voltaic arc and spark under high current/voltage, which causes harm to the system security. Researches on the over zero breaking protection circuit of permanent magnetism vacuum circuit breaker, designs the zero testing circuit. The circuit makes the breaker on or off when the current passes zero, which achieves the purpose of areless and improves the security and reliability of system.
